Disc brake rotor assembly with replaceable wear surfaces

1. A disc brake rotor assembly, comprising:

a central carrier having a first side, a second side, an outer peripheral edge, an inner peripheral edge and at least two locking mechanism windows spaced from and confined by said inner peripheral edge and said outer peripheral edge and extending from said first side to said second side;

at least two wear surfaces located on said first side and at least two wear surfaces located on said second side;

at least one locking mechanism disposed within said central carrier for selectively and directly securing and releasing an inside surface of said wear surfaces on said first side and an inside surface of said wear surfaces on said second side, said at least one locking mechanism comprising a block and a fastener selectively engagable with said block, said fastener extending inwardly from said outer peripheral edge of said carrier to said block; and

at least two locking mechanism fastener channels, connect said outer peripheral edge of said central carrier with said at least two locking mechanism windows respectively.

2. The disc brake rotor assembly of claim 1 , wherein at least two surface channels are located on said first side of said central carrier and at least two surface channels are located on said second side of said central carrier, said surface channels on said first side being laterally aligned with said surface channels on said second side of said central carrier.

3. The disc brake rotor assembly of claim 2 , wherein a circumferential groove is located on said first side of said central carrier, said groove being bounded by an inner wall and an outer wall and wherein said outer wall has at least a partial circumferential first lip.

4. The disc brake rotor assembly of claim 3 , wherein said second side of said central carrier has at least a partial circumferential second lip.

5. The disc brake rotor assembly of claim 4 , wherein each of said wear surfaces has at least one upstanding fining on each of said inside surfaces, respectively, said at least one upstanding fitting having a complementary shape to one of said surface channels.

6. The disc brake rotor assembly of claim 5 , wherein an arced groove is located on said inside surface of each of said wear surfaces and wherein said arced groove is bounded by an inner wall having a lip.

7. The disc brake rotor assembly of claim 6 , wherein at least two tabs are mounted on said inside surface of each of said wear surfaces and wherein an inside edge of each of said tabs has a lip.

8. The disc brake rotor assembly of claim 7 , wherein said fastener is located in one of said at least two locking mechanism fastener channels to selectively secure said block with said central carrier.

9. The disc brake rotor assembly of claim 8 , wherein said block has a channel along an upper portion, said channel along said upper portion of said block being bounded by at least two upstanding portions and said upstanding portions of said block designed to selectively engage with said lips of said tabs.

10. The disc brake rotor assembly of claim 9 , wherein said lip of said arced groove on one of said wear surfaces selectively engages with said first lip on said first side of said central carrier.

11. The disc brake rotor assembly of claim 10 , wherein said lip of said arced groove on another of said wear surfaces selectively engages with said at least partial circumferential second lip on said second side of said central carrier.

12. The disc brake rotor assembly of claim 1 , wherein said central carrier is constructed of a first material and said at least two wear surfaces on both said first side and said second side are constructed of a second material wherein said second material has greater thermal properties and wear properties than said first material.

13. The disc brake rotor assembly of claim 11 , wherein radial and/or lateral motion of said at least two wear surfaces on both said first side and said second side is selectively restrained by engagement of said at least one locking mechanism with said wear surfaces, by engagement with said at least one upstanding fitting with at least one of said surface channels, and by engagement of said first lip and said at least partial circumferential second lip with said wear surfaces.
